"Playing with pros on Sunday and walking (the course), you kind of feel - when you hit certain shots - you kind of feel the pressure that they would feel coming down the stretch," Crane said. "It definitely gets your blood pumping."

"Obviously, to get on the golf course with the President is no small task," Norris said. "Crane can play a little bit, too, and that's awesome - it's not everyday you get to meet the President of the United States.

"If I get cleared from the skipper (Astros manager Bo Porter), I will be there and I will be flying 95 (mph) down the freeway to get there, for sure."

Porter said it was a "great honor" to have the Astros directly associated with the president.

Crane invited the president to visit the Astros in Kissimmee, Porter said, but Obama acknowledged that his schedule was a little busy.
